BEER-FILTERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 426,965, dated April 29, 1890.

Application filed June 14, 1889. $erial No. 314,272. (No model.)

To aZZ whom it may concern.-

Be it known that I, PHILLIP SEIBEL, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Beer-Filtering Apparatuscs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This filtering apparatus is intended especially for beer or other liquids liable to foam, and has means for the removal of the foam into a settling-chamber, from which the liquid is withdrawn as it subsides. The apparatus is composed of two or more similar filters connected with the same system of circulatingpipes. v

Figure I is a side elevation of the apparatus. Fig. II is a side elevation of one of the filters with a head removed. Fig. III is a detail transverse section at III III, Fig. IV. Fig. IV is a detail vertical longitudinal section at IV IV, Fig. III. Fig. V is an enlarged detail section at V V, Fig. II. Fig. VI is a transverse vertical detail section at VI VI, Fig. IV. Fig. VII is an enlarged vertical longitudinal section of one of the upper transparent froth-chambers. Fig. VIII is an enlarged vertical longitudinal section of the lower transparent froth-chambers. Fig. IX is a detail vertical longitudinal section of part of the settling-chamber.

Referring to the drawings, 1 is a frame, shown as supported on wheels 2.

3 is a settlingchamber, shown to be of cylindrical form.

I is the induction pipe or hose through which the beer enters the apparatus. This pipe is connected by union-couplings 5 or otherwise with the pipe 6, leading to the glass chamber 7.

S is an open-topped pipe standing upright in thechainber 7, so that beer entering the chamber 7 will overflow into the pipe 8. The pipe 8 forms theupper end of a pipe 9, de scending from the chamber and furnished with a valve or cock 10, by which it may be partlyor wholly closed.

11 is a float having at bottom a valve 12, arranged to settle by gravity upon the top of the pipe 8 and close it, thus closing communication between the chamber 7 and pipe 8.

(See Fig. VIII.) .This float works on a stem 13, passing through a stuiiing-box 14:, and having at bottom a head 15, which works in an axial socket of the float.

13 is a plate attached to the top of the float and through which the stem passes. The construction is such that when the stem is drawn upward the head 15 comes against the plate 16, and the valve is lifted from the top of the pipe 8. The float 11 works in a chamber 17, forming an extension of the chamber 7. The chamber 17 communicates with the settling-chamber by a pipe 18, having a valve 19 and having a pressure-gage 20.

21 is a union-coupling allowing the disconnection of the pipe 18. The purpose of the pipe 18 is to allow the air and foam to pass from the chamber 17 into the settling-chamher 3.

22 is a pipe leading from the upper part of the induction-pipe 4: to the settling-chamber and having a stop-cock or valve 23 and unioncoupling 24. This pipe 22 is to allow the escape of air and foam from the induction-pipe of the settling-chamber.

From the lower part of the pipe 9 extends an upright pipe 25, the pipes being connected by a union or other coupling 26. This pipe 25 has at top a return-bend at 27, from which extends a pipe 28, leading to the pipe 18, and so to the settling-chamber. This pipe has a stop-cock or valve 29 and coupling 30.

31 is a standing frame having at'top a trunnion-bearing consisting of a contractile ring 32, open atone side, where are lugs 33 and 34, connected by a screw 35, which passes through a plain hole in the lug 33 and engages in a screw threaded hole of the lower lug 34. IVithin the bearing is a trunnion-block 36, traversed by two longitudinal pipes 37 and 38. To the pipe 37 is connected the descending end of the pipe 25, the connection being made by a coupling 39. By turning down the screw 35 the bearing is closed tight upon the block 36 and prevents its turning.

4-0 'is a tube having at the middle a collar or block 41, through which passes transversely the pipe 37, the joint being made tight between the pipe 37 and the collar. The end of the pipe37 is screwed or otherwise titted tight in the collar all of a tube 40. The tubes 40 and 40 have similar construction. They pass axially through the four filters 4-2, which filters are constructed alike, a description of one applying equally to the others. Each filter has an open-ended shell a3, with an axial tube at open at both ends, and havin radial ribs 45 extending from the tube et-l along the inside of the end 4.0, which forms part of the shell 43. These ribs have projections -:t7, forming bearing for a disk 48, of perforate metal, having around its margin a cylindrical flange 49. Upon the perforate disk 4.8 is laid a circular sheet 50, of wire-cloth, and upon the wirecloth a cloth 51, of any suitable porous material, and upon this is put filtering material 52, such as charcoal or any other suitable substance. The edges of the cloth are folded over inward and upon the material 52, and upon the edge of the cloth and the material 52 is laid a disk 53, composed of perforate metal or wire-cloth, above which is put more charcoal or othersuitable loose filtering material 5-1, which is held in place by another perforate disk Screw-bolts pass th rough the disks t8 and 55, and all between, to hold the parts together.

57 is a rubber band which surrounds the flange lf) and whose marginal inturn ed flanges 5S overlap the edges of the disks 4S and 55. Thus the filtering head is composed of a number of layers, as described, surrounded by a packing-band 57 58, adapted to fit in. the case 43, the rubber fitting tight inside the flange or wire 59 of the case.

(it) is the removable end or head of the case, whose margin rests upon the outer flange 58 ot' the rubber packing and the projections 47 of whose ribs l5 bear against the disk 55. Thus the filtering-head is held in place and the rubber packing compressed so as to prevent the passage of any liquid between the rubber and the rim 59. The tube +1 0 passes centrally through the filtering head and through the tube at and a tube 61, which projects inwardly from the casing-head 60 with a tight joint preventing any leak along the shaft. The tube 4-0 ends in a screwthreaded stud, which carries a nut 62, that bears against the outside of the head 60, and holds both it and the filtering-head in position. By the removal of the nut (32 the easing-head 60 and the filtering-head maybe removed.

63 are handles by which the head 60 may be lifted. The ends of the tubes at and U1 bear, respectively, against the perforate disks 4% and The ends to of the cases bear against the collars or blocks 41 or 41, as the case may be.

It will be seen that the filtering-head separates the filter into two chambers 6-1- and (55,the former of which is a receiving'chamber and the latter a discllarging-chamber. The receiving-chamber communicates with the tube it) by radial holes (36, which extend through the tubes l0 and t3]. (See Fig. III.) The liquid, after passing from the chamber (34 through the filtering material, escapes from the chamber (35 through a passage 67, made directly through. the end to of the case, and through the collar or block 41, into the pipe 38, whose end is screwed or otherwise fitted tight in the collar -;1-l, and which passes with a tight joint through the collar l-1,Wltlllll which it has holes 67, through which the liquid enters the pipe from two of the filt01':Clllmbers (55. The pipe 38 is coupled at (38 to an ascending pipe (5.), having a return-bend 7(), from which point it descends in a part 71, whichis connected with the discharge-pipe '72.

7 are air and foam pipes in communication with upper parts of the dischargc-chai'nbers 65. The pipes 7 have upward extensions 7t from the middle connected with glass vessels or chambers 75, through passages 7'6. The return-bends 27 and have the same altitude as that shown in respect to the latter, (7 0,) being at least equal in altitude with the top of the glass vessels, so that the latter will. be kept full of liquid when the apparatus is working. The glass chambers have'central orerflow-pipes 77, into which the contents of the chamber escape byholes 78, the overflow passing through a pipe 70 and descending pipe to the settling-chamber 3. The pipe 7'.) has couplings 81. and stop-cocks S2, and the descending pipe 80 has coupling 83 and stop-cock 84.

S5 is a transverse pipe connecting the discharge-chambers (35 of each pair of filters together, the pipe connecting with the lower parts of the chambers. From each of the pipes descends a pipe Sttwhich communicates at bottom with the settling-chamber. The pipes 86 have couplings 87 and stopcocks 89 is a stop-cock, with which may be connected a pipe leading to an air-compressor by which air is forced into the settling-chamher to force the contents out of the chamber.

U0 is a surface-gage indicating the depth of liquid in the settling-chamber.

Within the settling-ehan1ber is a valve 01, connected to the lever 92, whose free end carries a float 93, so that when the quantity of liquid in the settling-chamberincreases above a given point the valve is opened and allows the beer to flow through the valve-port 94 into the chamber 95. The chamber 95 has two openings 96 and 97. The first (9G) is con.- nected directly with the discharge-pipe, a three-way cook 98 being, however, placed in the pipe to ob eck or stop the discharge through the opening 216. The opening 97 connects the chamber )5 with the recei\ *ing-chamber Gel of a filter similar to the filters 4-2, already described, except that a simple axial screw-bolt )9 may be used to secure the parts together. The discliarging-chamber ($5 of this filter is connected by a pipe with the dischargingpipe 7 of the apparatus, the three-way cook 98 being interposed.

The construction and arrangementare such that the beer maybe made to pass directly from the chamber 95 to the discharge-pip ITS 72, or may be forced to pass through the filter. The latter position of the cock is shown in Fig. IX. The cook 98 may also be used to disconnect the discharge-pipe 72 from both the filter and'chamber 95. 7

101 is a waste-pipe from the settling-chamher, having in it a stop-cock 102.

103 is a plug stopping a discharge-hole in the chamber 95.

104 is the cover of av hand-hole through which access may be had to the settling-chain ber.

The operation of the apparatus may be shortly described as follows: When the apparatus is first put in operation, the cock 10 may be closed and the pipe 8 is closed by the valve 12. The cocks 19 and are open and the cook 29 closed. More or less froth or foam may be miXed'with the beer first entering through the pipe The air contained in the pipes, &c., will be first forced through the pipes 22 and 18 into the settling cylinder or chamber 3, and may be allowed to escape through the cook 89. As long as the glass vessel or chamber 7 contains foam the valve 12 is allowed to rest on and close the pipe 8, so that no foam can pass down the pipe 9, the foam passing up through the chamber 17 and through the pipe 18 to the settling-chamber. As soon as the glass "essel 7 is seen to contain beer without foam the float 11 and valve 12 are lifted by the stem 13, and the cook 10 being open the beer passes down the pipes 8 and 9 into the ascending pipe 25. The air is allowed to escape from the upper part of this pipe through the pipes 28 and 8 to the settling-chamber, the cock 29 having been opened. As soon as the air and any froth or foam which may be present have escaped the cook 29 is closed and the beer passes along the pipe 37 to the receiving-chambers 64 of all four of the filters 42 and drives the air therefrom through the filtering material into the' discharging-chambers 65. The air finds its way through the pipes 73 74, the glass chambers 75, and pipes 79 and S0 to the settling chamber or vessel 3. As soon as the glass vessels 75 show that the air and foam have escaped by the vessels being filled with beer without foam the cooks 82 are closed,

' but may be opened tempo1 arily at any time if there is an accumulation of foam. The beer flows from the discharging-chambers of the four filters into the pipe 38 and pipe 09 7O 71 to the discharge-pipe 72. It has been said that the cook 89 may be opened to allow the escape of air from the apparatus. This cock may be closed at any time, or a compressed-air pipe may be connected with it to reduce the quantity of foam and to force the beer from the settling-chamber. As the surface-level of the beer ascends in the settling-chamberit escapes through the filter 42 of the settling-chamber, or directly through the passage 96 to the discharge-pipe 72. It will be seen that when the apparatus is in regular operation the foam is treated without exposure to the air, and under constant pressure, and as soon as the beer is freed from foam in the settling-chamber it is returned to the main quantity. It will be seen by examination of Figs. I and 1V that the couplings 39 and 68 are in direct line with the axis of the block 36, so that the filters may be turned upon the coupling 39 and 6S and the block 36 when the screw 35 has been loosened, and any pipes which would interfere with such rotary movement uncoupled from the filters. NVhen it is desired to change the fil-. tering material in the filters, they are turned about one-fourth around, so as to bring the heads 43 of two of them upward, and after these have been repacked the filters are reversed and the other two repacked, when the filters are again turned edge up (in normal position) and are ready for use.

I claim as my invention 1. A filter divided into two chambers by a removable head composed of layers of filtering material, and a closed settling-chamber in communication with the upper and lower parts of the discharging-chamber of the filter, with cocks governing such communication, substantially as set forth.
